Subject: GPS and Prescription Agriculture

Background: Prescription agriculture is a method of farming where instead
of seeding/fertilizing/spraying the same amount over an entire
field, an amount appropriate for the slope and soil is applied.
This can be done by mapping the field and then using the map
to guide application. A key difficulty is in knowing where the
tractor is on the field. The global positioning system (GPS)
uses an ensemble of satellites sending coded information to
triangulate the latitude, longitude, and altitude of a receiver
to within a few feet. GPS receivers are down to about $1500.
Question: Are there any Prescription Agriculture GPS papers in recent
conference proceedings or journals? I am aware of only one
project in this area and it is being done by a farmer in
Indiana.
